SonicWall DNS Security Service for TZ280W 4YR | Cloud Licensing

Keep DNS traffic under control with a 4-year security service built for the SonicWall TZ280W. By inspecting and filtering DNS requests, this subscription helps block access to known malicious domains, reduce exposure to phishing infrastructure, and limit outbound connections to command-and-control hosts before they can establish a foothold. For security teams, DNS-layer enforcement adds an important control point without changing the user experience. It supports a cleaner policy model for branch offices, distributed users, and environments where endpoint-only defenses are not enough. The longer term also simplifies procurement and renewal management, which matters when you are standardizing protection across multiple sites. This service is a strong fit for organizations that want to raise the cost of attack without adding operational noise. It complements the TZ280W platform by extending its security posture beyond perimeter filtering and into domain resolution, where many modern threats first reveal themselves. For buyers comparing lower-cost options, the value is in consistent coverage, reduced risk, and fewer gaps between network and endpoint controls.
